    i dont know ,,,someone else will reply though who knows .
    wat i do know is that if u have any physics problems you can definately come in here and ask .One thing for physics ,is that you should have a course syllabus , look at that and see what you need to learn , you could show it to one of us , if your not sure wat all the topics are about and how much depth you need to go in to all of them , or anything else similar to that .Try and have a certain number of books and maybe a physics glossary from online.

    Perhaps you should be more specific in telling us what problems you have with the subjects. People find it easier to reply to specific questions than a broad one like yours.

    Stress and Strain

    Q: A copper wire of diameter d is stretched by a load hanging vertically from its lower end . The strain of the wire is 8.0x10^-4 . What's the strain in another copper wire of the same length but of diamteter 2d ?
    A: 2x10^-4

    Q: A light rod of length L hangs from the lower ends of two vertical wires M and N which are of the same natural length and diameter but ve differrent Young's moduli E1 and E2 respectively . A load is placed on the rod at a distance x from the wire M, so that the rod remains horizontal . What's the value of x in terms of L, E1 and E2 ?
    A: (E2L)/ (E1+E2 )


    Q - questions
    A - answer

    I would be glad anyone solve this as soon as possible . It would be great explain diagram , equations , steps by steps . Tnx . There ll be more questions.
